Driven by the new energy vehicle market, automotive sensors are unleashing huge market potential. In the era of intelligent electric vehicles, sensors are needed to monitor the working conditions of batteries and other components in real time, accurately transmit the surrounding environment, ensure the safety of vehicle operation, and promote the high-level development of autonomous driving.
This also means that the importance of sensors for automobiles is becoming increasingly prominent, and with the rapid increase in the penetration rate of smart electric vehicles, the entire industry will usher in historic development opportunities. With a history of more than 100 years, ROSHX, a German motor brand, continues to maintain an international leading position in the field of sensors, and "high precision" has become one of its important keywords for automotive sensors.
Why is the "high-precision" sensor placed in such an important position by Roshx?In the final analysis, this is related to the trend of electrification, intelligence and networking of new energy vehicles. Autonomous driving systems require vehicles to be able to accurately and sensitively capture changes in the vehicle's position and distance from surrounding objects, so as to determine whether the vehicle needs to react to steering, braking, etc., which requires more accurate sensors such as radar and cameras. For power management systems, new energy vehicles also put forward higher requirements for sensor accuracy.
Taking the current sensor as an example, there is a difference between new energy vehicles and traditional industrial power sensors", Garland, the current CEO of Roshx, said in an interview with reporters, "If you want to scientifically measure the power of new energy vehicles, you need to carry out sub-range measurement." In other words, current measurements are carried out with different accuracy for different battery levels of the vehicle. As a result, the current sensor needs to be highly accurate at small ranges. ”
Since the car needs to adapt to different temperature environments, RoshX also needs to ensure that the automotive sensor can achieve the accuracy of the full temperature zone. In other words, the same high accuracy can be measured in different temperature environments. Due to the deformation and elastic changes of some materials and devices at high or low temperatures, the design accuracy of RoshX sensors needs to meet higher standards.
For automobiles, the repeatability of the car is very important, that is, when the car is used for one year, two years, five years or even more, the repeatability accuracy of the car will decrease. The accuracy of the sensor needs to be guaranteed to remain within the design range after 15 years of use, even if there are problems such as material fatigue, deformation, and accuracy degradation. To achieve this standard, Roshx needs to be calibrated with at least 3 times the accuracy of the product design.
